I believe if you are usingOP miles that CO does not give hardly an availability to central and south america during christmas time. I know some flts are still showing no seats at all not even easypass. Well as long as there are revenue seats open, you can call an agent and they will book you an easypass seat even on copa. If you dont want to use easypass then its pretty much a pipe dream. To bad you cant waitlist Copa. Godd luck. I hope you get down to B.A.
